Definitions

  • the invention relates to an inflator-equipped housing for an airbag and a side airbag unit having the inflator-equipped housing structure for installation to the internal region of a seat in a vehicle.
  • An airbag unit for use in a vehicle incorporates an airbag which deploys through inflation by the inflow of gas generated by an inflator.
  • the inflator is attached to and secured by a housing to which the airbag is attached.
  • the gas supplied by the inflator is guided into the airbag through the housing.
  • the inflator normally has a cylindrical shape, and the housing is a normally a hollow cylinder with open ends.
  • the inflator is inserted into the housing through one end and supported therein.
  • the gas generated by the inflator flows along the length of the housing and enters the airbag from the open ends of the housing.
  • the direction in which the inflated airbag deploys is extremely important for an airbag unit used in a vehicle. This is especially true for a side airbag unit because the airbag must inflate very rapidly into a narrow space between the person sitting in the seat and the side of the vehicle structure. It is possible to more securely set the direction of airbag deployment in a manner that the housing discharges gas toward the desired deploying direction.
  • Gas discharged in the airbag deployment direction generates thrust to the inflator and housing in the opposite direction of the gas discharge direction.
  • This thrust can pose a problem in regard to transportation and storage of the inflator before it is installed to the vehicle.
  • the inflator is liable to be thermally damaged if exposed to fire or other heat source on transportation, or at the factory where it is made or at the vehicle assembly facility. If the inflator becomes thermally damaged, the gas may be accidentally discharged from the inflator and generate thrust which drives the inflator and housing through the air and thus cause it to become a dangerous projectile.
  • Reference Document 1 describes an inflator, which is not attached to the housing but exists as a separate component.
  • Reference Document 1 of " JIG FOR TRANSPORTING INFLATOR” describes a simple structure which has the purpose of preventing the inflator from becoming a projectile should it discharge the gas held therein during transportation as a result of thermal damage.
  • a curved cover plate in which multiple leakage holes have been formed, is fixed to a cylindrical inflator by attachment bands to cover a discharge port which is formed on the inflator, and is spaced apart from the gas discharge port by spacers mounted on the inner surface of the cover plate to allow the part of gas flown from the gas discharge port to escape through the leakage holes.
  • the present invention has been construed in light of the arforesaid shortcoming in the related art as a side airbag unit with inflator-equipping housing for installation to a vehicle wherein an inflator can be attached with a housing which discharges gas in a desired and specific direction where the airbag inflates and deploys, the thrust generated in a direction opposing the direction of the discharge gas flow can be suppressed should thermal damage to the inflator result in accidental gas discharge, and it can be properly ensured the normal operation capability of the side airbag unit.
  • the inflator-equipped housing for airbag comprises a cylindrically hollow shaped metal sub-housing having an open gas discharge port at each end; a cylindrically shaped inflator inserted into the sub-housing through either gas discharge port and secured therein, the inflator having gas guide ports formed in its circumferential wall as means of guiding an airbag inflation gas there through; a 1st orifice in the sub-housing positioned in proximity to the gas guide ports and substantially facing an airbag deployment direction; a 2nd orifice in the sub-housing separated from the 1st orifice along an circumferential direction of the sub-housing; and a plug installed in and sealing the 2nd orifice; wherein the plug is of thermo-soluble resin, and includes a nipple part which has an external diameter dimensioned to contact with an internal periphery of the 2nd orifice and a flange part which extends from the nipple part and contacts with an internal surface of the sub-housing.
  • the nipple part of the plug is inserted into the 2nd orifice from the internal side of the sub-housing and protrudes from the external surface of the sub-housing when the flange part is in contact with the internal surface of the sub-housing.
  • a lip part is formed on the nipple part in order to prevent a removal of the nipple part from the 2nd orifice, and is located at a position outside of the external surface of the sub-housing when the flange part is in contact with the internal surface of the sub-housing by inserting the nipple part into the 2nd orifice from the internal side of the sub-housing so as to protrude it from the external surface of the sub-housing.
  • protruding ribs are formed at appropriate locations on the interval surface of the sub-housing as means of securing the inflator within the sub-housing.
  • the nipple part is formed to a substantially same cross section as the 2nd orifice, and the flange part is formed to a substantially same curvature as the inner surface of the sub-housing.
  • the 2nd orifice is formed at a location opposite to and facing the 1st orifice.
  • the present invention of the inflator-equipped housing for an airbag and side airbag unit therewith have the effects that an inflator can be attached with a housing which discharges gas in a desired and specific direction where the airbag inflates and deploys; the thrust generated in a direction opposing the direction of the discharge gas flow can be suppressed should thermal damage to the inflator result in accidental gas discharge; and it can be properly ensured the normal operation capability of the side airbag unit.
  • FIG. 1 illustrates a side airbag unit 1 which is integrally installed to a seat back 2a of a vehicle seat 2, side airbag unit 1 primarily comprising an inflator-equipped housing 3, and a fabric airbag 4 residing within the housing 3 in a folded condition.
  • an inflator 5 (to be described subsequently) of the side airbag unit 1 generates a gas which flows into the airbag 4 through a sub-housing 6, thus propagating the inflation and deployment of the airbag 4 toward the front of the vehicle from the side of the seat back 2a.
  • the airbag 4 Upon activation of the side airbag unit 1, the airbag 4 begins to inflate while concurrently entering the narrow space between the person sitting in the seat 2 and the vehicle itself, and continues to inflate while moving toward the front of the vehicle along the side of the seat 2, thus protecting the person from the shock of the side impact.
  • the inflator-equipped housing 3 includes the sub-housing 6, the inflator 5, and a plug 7.
  • the sub-housing 6 is a hollow cylindrical metal structure of uniform thickness. While this embodiment describes the sub-housing 6 as a hollow cylinder, it may also be formed as a tube-like structure having angular walls. Both axial ends of the sub-housing 6 are open so as to form gas discharge ports 8.
  • a mounting bolt 9 is installed near each end of the sub-housing 6, each mounting bold 9 protruding outward through the side of the sub-housing 6 in a radial direction. Threaded nuts (not shown in the drawings) are used to secure the mounting bolts 9 to the seat back 2a as means of attaching the sub-housing 6 to the seat back 2a.
  • the cylindrically shaped inflator 5 resides within the sub-housing 6.
  • the inflator 5 is cylindrical in shape so as to correspond to the hollow cylindrical space defined within the sub-housing 6.
  • the inflator 5 may also be formed as a tube-like structure with angular walls if the sub-housing 6 were to be structured in the same configuration.
  • the external diameter of the inflator 5 is formed to a slightly smaller dimension than the internal diameter of the sub-housing 6 so as to allow a small gap to exist there between.
  • Multiple radially oriented gas guide ports 10 are formed at an appropriate position in the circumferential wall 5a of the inflator 5.
  • the gas guide ports 10 are provided as means of directing the discharge of inflation gas into the airbag 4.
  • the inflator 5 is axially aligned to and inserted into the sub-housing 6 from either gas discharge port 8 in a direction toward the opposing gas discharge port 8.
  • the end part 5b of the inflator 5 may be inserted into the sub-housing 6 to an extent whereby the opposing end part 5c remains protruding from the sub-housing 6.
  • the end part 5b may also be inserted up to the gas discharge port 8.
  • the end part 5c of the inflator 5 may be enclosed by the sub-housing 6.
  • Ribs 11 are formed at appropriate points on the inner surface 6a of the sub-housing 6, and protrude into the internal space of the sub-housing 6 as means of maintaining the inflator 5 at a specific location therein. Ribs 11 protrude a distance greater than the gap between the circumferential wall 5a of the inflator 5 and the inner surface 6a of the sub-housing 6.
  • the ribs 11 are press-formed ridges extending the inside of the sub-housing 6 from the outside thereof.
  • the ribs 11 may be formed by various manners.
  • a 1st orifice 12 is formed in the wall of the sub-housing 6 in proximity to the gas guide port 10 in the inflator 5.
  • the 1st orifice 12 faces the approximate direction of inflation of the airbag 4.
  • the 1st orifice 12 faces the front of the vehicle from its position on the side of the seat 2.
  • the gas generated by the inflator 5 flows through the gas guide ports 10 and is discharged from the gas discharge ports 8 through the gap between the sub-housing 6 and inflator 5, while concurrently flowing through the 1st orifice 12 in the inflation direction of the airbag 4.
  • a 2nd orifice 13 is formed in the wall of the sub-housing 6 at a position along the radial circumference separated from the 1st orifice 12.
  • the 2nd orifice 13 is formed to a smaller dimension than the 1st orifice 12, and may be provided in the form of a single orifice or multiple orifices. It is preferable that the 1st and 2nd orifices 12 and 13 are point symmetrical in relation to the axial center of the sub-housing 6, or linear symmetrical along a line at a right angle to the axial centerline of the sub-housing 6. In this embodiment, the 2nd orifice 13 is positioned directly across from the 1 st orifice 12 on the radial axis of the sub-housing 6.
  • a plug 7 is installed to the 2nd orifice 13 from the internal side of the sub-housing 6.
  • the plug 7 thus forms a seal which prevents gas from flowing out through the 2nd orifice 13.
  • the plug 7 is a single structure primarily comprising a flange part 7a and a nipple part 7b integrally formed above the flange part 7a.
  • the entire plug 7 is constructed of a heat fusibility resin which will soften and melt in a high heat environment such as that generated by a fire or other thermal source.
  • the external diameter of the nipple part 7b is formed so as to stick in the inner periphery of the 2nd orifice 13.
  • the external dimension of the nipple part 7b is made to the approximately same dimension as the 2nd orifice 13.
  • the nipple part 7b is formed to a cross section shaped essentially the same as that of the 2nd orifice 13.
  • the flange part 7a is formed as an approximately square plate-like structure which extends radially outward beneath the nipple part 7b.
  • the flange part 7a has a curved surface which contacts the internal surface 6a of the sub-housing 6.
  • the upper surface of the flange part 7a is formed to the same curved profile as that of the internal surface 6a of the sub-housing 6.
  • the flange part 7a is made to a thickness approximately equivalent to that of the gap between the inflator 5 and the sub-housing 6.
  • nipple part 7b is inserted into the 2nd orifice 13 from the internal side of the sub-housing 6, thus resulting in the upper surface of the flange part 7a coming into contact with the inner surface 6a of the sub-housing 6, and nipple part 7b extending above the external surface 6b of the sub-housing 6 to an extent shown by the letter 'H' in Fig. 7 .
  • a lip part 7c is integrally formed to the nipple part 7b.
  • the lip part 7c is inserted through the 2nd orifice 13 from the internal side of the sub-housing 6, and is separated from the sub-housing external surface 6b distance 'h' ( Fig. 7 ) when the upper surface of the flange part 7a is in contact with the sub-housing inner surface 6a.
  • the lip part 7c is formed as a ring-shaped protrusion extending radially outward from the nipple part 7b.
  • the lip part 7c engages the sub-housing external surface 6b to form a sandwich-like structure in which the lip part 7c and flange part 7a press oppositely against the sub-housing 6 to secure the plug 7 in place.
  • the installation of the nipple part 7b into the 2nd orifice 13 is secure due to the plug 7 being made from resin.
  • the side airbag unit 1 includes the inflator-equipped housing 3, fabric airbag 4, and an airbag case 14 which contains the airbag 4 and inflator-equipped housing 3.
  • the airbag 4 the structure of which is well known in the art, is in a folded configuration with one extremity fixedly attached to the inflator 5 through the sub-housing 6.
  • the one extremity of the airbag 4 is attached to the inflator-equipped housing 3 so as to completely envelope the gas discharge ports 8, 1 st orifice 12, and 2nd orifice 13.
  • This structure allows all of the gas discharged from the inflator 5 to enter the airbag 4 through the sub-housing 6, and to inflate the folded airbag 4 to a fully deployed condition.
  • the airbag case 14 is a box-like structure, made of a resin, which includes a cover flap 14a.
  • the folded airbag 4 and the inflator-equipped housing 3 to which the airbag 4 is attached are inserted into the airbag case 14 through the open cover flap 14a.
  • the sub-housing mounting bolts 9 extend outwards through holes formed in the cover flap 14a of the airbag case 14.
  • Nuts 15 fasten to the mounting bolts 9 on the external side of the airbag case 14, and thus serve as means of securing the cover flap 14a in a closed condition while also securing the inflator-equipped housing 3 to the airbag case 14. As shown in the Fig.
  • the inflator-equipped housing 3 is located in the upper region of the airbag case 14, while the folded airbag 4 is located in the lower region. Therefore, the 1st orifice 12, which faces toward the direction of the deployment of the airbag 4, is oriented downward.
  • Separation line 16 is formed in the airbag case 14 at a location substantially opposing the 1st orifice 12. As illustrated in the Fig. 9 orientation, the separation line 16 is formed in an appropriate length on the bottom of the airbag case 14, in the lengthwise direction relative to the inflator-equipped housing 3, so as to oppose the 1st orifice 12.
  • the separation line 16 may comprise a row of intermittent slits or notches, or a thin portion formed in the airbag case 14.
  • the separation line 16 exists as a demarcation line in the airbag case 14 when the airbag 4 remains undeployed, but will become the line of separation along which the airbag case 14 ruptures to form deployment opening 17 by the inflation force when the airbag 4 is deployed.
  • a hinge part 18 may be provided at the top of the airbag case 14 (relative to the view in Fig. 9 ) opposing to the separation line 16. While this embodiment describes the deployment opening 17 being formed from depressed parts along the separation line 16, other structures allowing the separation of the case 14 to be also employed. For example, a pre-formed slit or a hinged door-like structure provided adjacent to the opening is applicable as other means.
  • the inflator-equipped housing 3 is handled as a separate component during transport, or stored as a separate component at the factory where it is manufactured or at the vehicle assembly site. Should the inflator-equipped housing 3 be damaged as a result of exposure to excessive heat in case of a fire and so on, the inflation gas will be directed through the gas guide port 10. At the same time, the heat will melt the plug 7 resulting in it being driven out of the 2nd orifice 13. To be specific, at least, the boundary portion between the flange part 7a and nipple part 7b will soften and break as a result of the excessive heat, thus leading to the destruction of the plug 7.
  • the inflator 5 will reach its ignition point causing the generation and discharge of gas.
  • the gas escaping from the gas guide port 10 will flow into and fill the gap between the sub-housing 6 and inflator 5, and then flow out of the sub-housing 6 through the 1st orifice 12 and the gas discharge ports 8.
  • the pressure of the gas will drive the plug 7 out of the sub-housing 6 and thus open the 2nd orifice 13.
  • the opened 2nd orifice 13 allows the escape of the gas there from, resulting in the generation of thrust in a direction counter to that generated by the escape of gas from the 1st orifice 12, thus canceling out a unidirectional thrust applied to the inflator 5.
  • this structure makes it possible to counteract the thrust generated by the gas escaping from the 1st orifice 12 in the deployment direction of the airbag 4 by means of thrust generated by the gas escaping from the oppositely located 2nd orifice 13, and thus prevents a strong unidirectional thrust from being applied to the inflator-equipped housing 3.
  • the thrust generated by the escape of gas from the 2nd orifice 13 counteracts and weakens the thrust generated by the gas escaping from the 1 st orifice 12.
  • the thrust generated by gas escaping from the 2nd orifice 13 would have the effect of reducing the thrust generated by the gas escaping from the 1st orifice 12.
  • Establishing the 2nd orifice 13 to a size slightly smaller than the 1st orifice 12 increases the sealing effect provided by the plug 7. It is preferable that the plug 7 may be made to smaller dimensions as it will hasten the thermal destruction speed at which the nipple part 7b and its surrounding part become thermally damaged and expose the 2nd orifice 13.
  • the side airbag unit 1 which incorporates the inflator-equipped housing 3. It is preferable that the side airbag unit 1 is installed to a vehicle in an orientation wherein the airbag 4 will inflate in the region between the occupant and internal side of the vehicle while deploying toward the front of the vehicle.
  • the inflator-equipped housing 3 is installed to the seat back 2a so that the 1st orifice 12 faces the front of the vehicle in the region between the occupant and internal side of the vehicle.
  • the inflator-equipped housing 3 is placed in the airbag case 14, with the folded airbag 4 attached, before the installation to the vehicle.
  • the airbag case 14 is then installed within the seat back 2a by secured with reinforcement in the seat back 2a of the seat 2. This is the finished configuration of the vehicular side airbag unit 1.
  • gas generated by the inflator 5 flows into the airbag 4 from the gas guide port 10 through the sub-housing 6.
  • the plug 7 remains seated in and sealing the 2nd orifice 13.
  • Most of the gas generated by the inflator 5 flows out from the 1st orifice 12, while some gas also flows out of the gas discharge ports 8 in the sub-housing 6.
  • the thrust generated by the gas flowing out of the 1st orifice 12 is received by the seat back 2a reinforcement, and the pressure of that gas is concentrated along the airbag 4 deployment direction due to the 1st orifice 12 facing the approximate deployment direction.
  • the airbag 4 inflates and deploys efficiently in predominantly that direction from within the airbag case 14.
  • the separation line 16 which is formed on the underside of the airbag case 14 and located substantially in opposition to the 1st orifice 12, ruptures by the pressure applied from the inflating airbag 4, thus creating the deployment opening 17 through which the airbag 4 may exit the airbag case 14.
  • the airbag 4 then flies out of the airbag case 14, enters the space between the occupant sitting in the vehicle seat 2 and the internal side of the vehicle, and continues to deploy along the side of the vehicle seat 2 toward the front of the vehicle, and thus cushions the impact applied to the occupant.
  • the side airbag unit 1 is thus able to offer a superior level of protection to the vehicle occupant.
  • the nipple part 71b, 72b, or 73b may be established to a dimension in height whereby it at least protrudes from the external surface 6b of the sub-housing 6 when the flange part 71 a, 72a, or 73 a is in contact with the internal surface 6a of the sub-housing 6.
